Drilling 8.75 for LBP

I was looking and didnt find anything. Has anyone drilled their SBP 8.75 axles for the LBP and have you had any problems? How much did it end up costing you and do you think it will hold up to 400 to 450hp? I am mostly a around town driver and a little draggin every now and then. Also if someone has some pictures I would appreciate it.

Appreciate advice.

Thanks
Jeff
